Earlier this year, I was invited to share some thoughts as part of SpecialEffect, with the Tuke Sprint team. To cut a short story shorter, they created six interactive experiences for PC and Mac, which you can grab and learn all about over at the Accessible GameBase.

"Fluids" (pictured above) is a great place to start, which can respond to the most gentle of finger-tip movements within the range of a web-cam. It's other worldly and very impressive when set-up well.

I really hope the team get to develop these further, because even as they stand (unfinished), they can be wonderfully accessible and highly effective activities for people of almost all abilities.
